Apps are great go-to garden resources for several reasons: It's easier to swipe your smartphone while pulling weeds than flip to page 327 of a how-to book; resources are typically utilitarian and easily accessed; and if you happen to be space deprived, book storage isn't an issue. Here are five worthy downloads. -- Jessica Damiano
Burpee Garden Coach (free, via text -- message and data charges may apply) Not an app in the traditional sense, Burpee Garden Coach is more of a zone-specific subscription. Instead of downloading an app onto a smartphone, users text their ZIP code to 80998, essentially signing up to receive notices throughout the season that are timed to coincide with the progress of their vegetable gardens, according to where they live. The well-timed notices include garden reminders, how-to tips, variety-specific advice, harvesting techniques, storage information, and even recipes for cooking your harvest.

BirdLog (North American version, $10 iPhone, Android) With just one click, this app enables birders to report their field sightings instantly to eBird, the joint Audubon-Cornell Lab of Ornithology worldwide citizen science program.
